A Complete Guide to Jigsaw Blades
Jigsaw blades can be used when undertaking a DIY project in conjunction with the use of a jigsaw. It is important to make sure that the blades you are using are the correct ones for the job. Before starting a task, you may need to assess whether you actually need a different type of jigsaw blade to finish your project to a better standard. There are various kinds of blades appropriate for different types of projects.
High-speed steel or bi-metal blades used mainly for hard or soft wood and light metal cutting. Cobalt steel is a much harder material than high speed steel or bi-metal blades and normally has a longer usage life. Cobalt steel is also less likely to break during application.
Carbide grit blades are used mainly to cut plaster board or masonry board while scrolling blades are excellent for getting to tight corners because the narrower blades make it easier to turn though tighter corners in your cutting project.
Plastics and Ceramics
There are a range of jigsaw blades that are suitable for every situation and there are even blades that will cut plastic and ceramics. This type of fine edged blade has the appearance of having no ‘teeth’ to speak of, but its fine edge is carbide coated which allows you to cut through tiles using your jigsaw.
Metal and Acrylic Plastic Cutting
You can also buy jigsaw blades suitable for cutting metal and piping. The teeth have a fine structure like that of a metal hacksaw to cope with the cutting of materials that produce filings. The same applies to blades used for cutting acrylic glass. They also have a very fine edge for minimal ripping or shattering.
If you are cutting laminate flooring, it is recommended that you use a special laminate blade. Using this type of blade will reduce the chances of ripping the laminate when you cut the pieces to length. It also gives a clean cut and won’t tear the internal material.
Each blade has its own cutting style and tooth thickness. For finer jobs and higher accuracy, a finer blade with smaller teeth will offer a smoother cut edge. If you are rough cutting plywood and you are not worried about the finished edge, you can use a medium tooth blade for softer wood.
If your project is large or if you are fitting a new kitchen, you will need suitable blades for cutting through thick worktops. Most worktops are made from particle board and the blade needs to be right for that project.
Although these ideas offer a guide to help you choose the right jigsaw blade for the right job, do not start cutting if you are not entirely sure you have the right cutting tool. Check your local DIY store or ask an expert for advice before you start your home project. Jigsaw blades get extremely hot so keep safety in mind and don’t touch the metal of the blade until it has cooled down.
